"Simple 2.1 Surround Speaker System " . Here I have used three TDA 2030 IC for making signal amplification . Here you need a sub filter extra ( Sub filter circuit diagram link showing below ) . This project mostly used in computer . Part list and applications are showing below.
| Component No: | Value | Usage |
| All C1 | 100MF | Grounding |
| All C2 | 100nF | Grounding |
| All C3 | 100nF | Grounding |
| All C4 | 100MF | Grounding |
| All C5 | 100MF | Feedback |
| All C6 | 100MF | Audio Coupling |
| All C7 | 220nF | Noise Grounding |
| All R1 | 1K | |
| All R2 | 10K ( Not 1K ) | |
| All R3 | 22K | |
| All R4 | 22K (Not 1K ) | |
| All RV1 | 100K | Volume Controlling |
| All D1 To D2 | IN4007 | Potential Breaking |
| U1 To U6 | TDA2030 | Amplification |
Applications* 2.1 Surround Amplifier
* 2.1 Home Theater
